I imagine the crossover change will not be too difficult, cabinet will have to be modified some, should be fun

To really cut costs, I might try these tweeters instead of the HDS:

Yes - I know it wouldn't be fair to call them Elsinores anymore at that point - but, who knows, might turn out well?

You are right, Elsinore they would not be, if built this way. But, not to discourage innovation and experimentation you may want to start a new thread for your speaker.

Good luck.

Hello all,
I thought I might post some pictures from my "work in progress" build of the Elsinores.

First, 1 inch (25mm) thick mdf is hard to come by, so I had to buy several sheets of 1/2" (12.5mm) MDF from Home Depot and glue them together.

Lots of Glue:

Lots of Clamps!

Lots of clamps and a great set of tools courtesy of ThomasW (who is an active poster and a moderator over on Hometheatertalk). The tools are great, but Thomas' guidance and expertise was by far the most valuable part of this whole project.

Next day, time to start cutting them to size, courtesy of these saws:

and

and the first pass:

Now, time to start drafting!! This is where Thomas' experience REALLY kicks in, I would have severely screwed this up if I'd been doing it on my own, but with his guidance it was a snap:

One more question, I bought a pair of flared ports from parts express, they are 95mm interior diameter. How long should they be cut down to in order to tune the box properly?

The construction drawings indicate the port should be 90mm wide and 80mm long. Since mine is 95mm wide, should I make it 85mm long to compensate?

As long as there are no pockets laminated 1/2" will be better than 1". 1/2" MDF & 1/2" Baltic Birch would be even better.

since 87mm internal dia = 80mm length
and
90mm ID = 88mm

i would imagine 95mm ID would = ~100-105mm length

Also because they are flared the length begins and ends at the mid point of the flare as per diagram below.

Things are moving along, here's the latest in the build.

Got the braces installed on the rear panels:

And the "stiffening panel" behind the tweeter. Since the tweeter is sealed (not vented), we'll put another board on the back to completely isolate the tweeter from the mid/bass soundwaves.

Sanding out the tweeter leads:

CLAMPS!

Even cooler clamps:

The manly nail gun we used to lock down each side and the mid brace while the glue sets:

Yes, it really is that insane:

Excellent! Terrific phtos, you obviously also know how to use a camera. What did you use (hinting at my other passion)?
